reviews: It is not as good as described but plenty good for the price. The solar charger is enough to keep it fully charged but would take days or weeks to charge if empty. The capacity is no where near 30000 mAhr but it charges a phone twice on one charge and does so quickly.

reviews: I first bought some of these as Christmas stocking-stuffers more than a year ago. Two of our kids live in Hurricane alley and use them almost daily, even when the weather is good! These are well-made with good build quality and even the oldest ones still hold a charge. I have now (7/17) bought a total of 6 with equally good results. Perfect compatibility with iPhone 6/7, LG and other smartphones as well as handheld games etc.
Cons: charging LEDs are too bright, flashlight LED too dim; no adapter for iPhone 6/7 (just use the cord that comes with the phone)
Wishlist: 12v model at this price point
Tip: Solar charging works even when cloudy, but DC charging is faster.

reviews: Pressing the on off button twice turns on or off the blue light.
I suspect that the fitting of an "Ultra Violet" LED was an error on the part of the manufacturer
It would have been more useful if an "Ultra Bright" white LED had been fitted instead
Using it to recharge my phone and vaping machine at the moment, all seems to be going well!
Maybe I'll review further following a bit more use...

reviews: I purchased 3 of these. Power rating is double of what you get. Solar charging does not work on any one of the three. The charge indication never gets past the first blinking LED when solar charging.. There is NO documentation. What does the on/off switch do? Charges fine when connected to USB. Provides power to my GoPro fine whether ON or OFF. Just delivers only about half the rated power. Price is High compared to other 15000 mA USB storage devices. Lack of documentation is a total killer. Perhaps it can actually perform as stated but they don't bother to explain
the functions. Do not waste your money on this product.

reviews: I cannot turn off the single blue light. By being on 24hrs/day it loses charge.
If I could turn this off and it help charge I'd change my rating, as it is it is pretty useless.
